我需要使用GitHub API获取存储库列表,搜索必须在单击按钮和更改带有许可证的selectBox上进行
import React, { useState, useEffect, useCallback } from "react";
import axios from "axios";
import moment from "moment";
import { Layout } from "./../Layout";
import { List } from "./../List";
import { Loader } from "./../Loader";
import { Header } from "./../Header";
import { Search } from "./../Search";
import { Licenses } from "./../Licenses";
import "./App.css";
export const App = () => {
const [data, setData] = useState([]);
const [isLoading, setIsLoading] = useState(false);
const [hasError, setHasError] = useState(false);
const [nameSearch, setNameSearch] = useState("");
const [license, setLicense] = useState({});
const fetchData = useCallback(async () => {
setHasError(false);
setIsLoading(true);
try {
const prevMonth = moment()
.subtract(30, "days")
.format("YYYY-MM-DD");
const licenseKey = (license && license.key) || "";
const response = await axios(
`https://api.github.com/search/repositories?q=${nameSearch}+in:name+language:javascript+created:${prevMonth}${
licenseKey ? `+license:${licenseKey}` : ""
}&sort=stars&order=desc`
);
setData(response.data.items);
} catch (error) {
setHasError(true);
setData([]);
}
setIsLoading(false);
}, [license]);
useEffect(() => {
fetchData();
}, [fetchData]);
return (
<Layout>
<Header>
<Search
handleSearchChange={setNameSearch}
nameSearch={nameSearch}
isLoading={isLoading}
onSearch={fetchData}
/>
<Licenses license={license} handleLicenseChange={setLicense} />
</Header>
<main>
{hasError && <div>Error</div>}
{isLoading ? <Loader /> : <List data={data} />}
</main>
</Layout>
);
};
首先,我得到警告
带有警告编译。
./src/components/App/App.js
第42:6行:React Hook useCallback缺少依赖项:'nameSearch'。包括它或删除依赖项数组react-hooks / exhaustive-deps
而且我的搜索无法正常工作,因为
nameSearch
在查询字符串中始终为空。如何使搜索工作?
最佳答案
尝试将nameSearch添加到useCallback的依赖项列表中:
const fetchData = useCallback(async () => {
...
}, [license, nameSearch]);
并确保在
Search.js
中实际使用了setNameSearch,以便它具有一个值。
